Firstly; I am afraid this is going to be fairly brutal, but it will, at least, be an honest critique. None of it intended to crucify. Hopefully it will give you a direction to grow towards.
You asked about the profile page specifically. I looked on an iPad and some text was overlaying other text, so that would be a fall at the first hurdle for any potential employer/client.
The next thing I see are some lurid, fluorescent, unnecessary gradients that lead me to an equally gratuitous animation. Neither add anything to the experience. It then goes on to repeat some of the text below and into ‘showcasing’ some work, which again repeats the content of the work pages. All of this sits behind your title and menu, all but obscuring it and in turn, they hinder the video.
The text itself reads like it has been written by a school-leaver and I can see from your picture that you are not. You need to understand who you are trying to appeal to and why. No one is interested in your passion. They are interested in how your work could help their business. That’s it. It’s as hard-nosed as that. Some background information about the person they are working with can be useful, but this is all written in a ‘what I did on my holidays' sort of way. Why even mention your disability? TI think it is personally tragic that you have a disability, and for that I am sorry to hear, but from a work and business service, it should not have any bearing, beyond how you personally overcome and thrive. The client doesn’t need to know this, or you risk the sympathy vote and I am sure like anyone, you would want the quality of your work to be why you get jobs.
You say that you have seven years of experience. I am guessing that this is self-taught experience – again, remember I am trying to be brutally honest here and not hurtful. – It shows. Overall, you come across to me as someone who had an early life doing something entirely different, then decided that, as you feel you are a creative person, you wanted to do something with that going forward. I am guessing you have never had either a formal design education, or had hands-on experience in a good design studio. You really need to do one or the other.
Normally, I would advocate getting yourself educated at a good bricks and mortar university, but as I don’t know the level of your disability, I have no idea how feasible this is. It may be that, in your case, a remote education from a good, accredited university (not from the countless private, self-ascribed ‘universities’).
Your understanding of typography is, I am afraid to say, woefully lacking. Hierarchy, is all but non-existent. I don’t really want to go through piece-by-piece and spend the day picking holes in individual pieces, but suffice it to say there are enough rookie mistakes which display a lack of formal,knowledge. What you have done (and say in your profile) comes across as vehicles for self expression. If that is your goal, become a fine artist.
Design is about problem-solving and communication. It is about using typography and image to convey a message to the right people in the correct tone of voice. For this a true understanding of typography is absolutely critical. If you don’t have this, you will never be able to practice as a successful designer. It is exactly this, along with critical thinking and a host of other necessary fundamental principles that a formal education gives you. Or at least it gives you the grounding to be able to spend the rest of your life perfecting it. I have been doing this for around 30 years now and I still feel like I have only scratched the surface of understanding typography.
Overall, I think you need to fill these gaps in your knowledge before setting your stall out as a professional graphic designer. You are competing in a very tough market, so, you need to make sure you do as much as you can to give yourself the best chance you can. Knowing software is not enough, any more that knowing how to use a knife will make you a Michelin-starred chef.
Finally,, stay away from the competition sites. They are only a race to the bottom.
