I'm glad you came up with it your self. Too many people just find a word press theme, change a few colours, call it their own and then ask for feedback as if they've just created something unique.
I like what you've done so far, but there's an element of, "I do this, and this, oh I do this too, oh, oh, and this". I would really narrow down what your core services are, otherwise you're going to struggle to compete against people who specialise in each a couple of those areas, with the internet there is a never ending stream of specialists available to people. For instance, a customer is unlikely to care whether their 'website guy' can draw or not, they will want them to be spending time trying to improve their website, not learning how to draw different perspectives.
I think your illustrations detract from the website because they aren't up to par with the standard set by the website, some of them look unfinished if I'm honest and a couple just look amateurish at best, mainly iScream and Koi Fish.. I like the pig in the mud one, but the mud looks more like a wooden pedestal or something. As for your owl, I would digitise that drawing and put it up instead of that one, unless you're going to focus on becoming an artist of some sort, but I'm going to make a wild assumption and say that you're probably more invested in web/graphic design.
I think also a number of your logo's are lacking in creativity, some just look like titles you might find on a website. Your print media section needs to have more variety, especially for the content slider and photos of actual t shirts will look much better than example graphics.
