Hi Paul, some nice work in there, but the site design is fairly poor.
I see the work ( ....if i can know to click on the graphics). The work is displayed in a mish mash of sizes and shapes. There is no info on you. it's just a selection of poorly presented work.
It fails at the first hurdle as it is a poor piece of communication.
If you are are technical illustrator then don't try and be a web designer. Find someone who can add value to your work by showcasing your talents to the commercial field more effectively.
True it's a website (...ish) but its a naff one ( albiet, with some decent content on it).
Make a business decision to invest in your talent by finding the talent to make you shine.
Don't meddle or play with showcasing your work, even if it's for cost. You are what you wear. Invest in someones web skills and you will thrive.
