I may be able to do one in the future. But I just haven't had much time to rework it properly. I did try a quick fix in altering the colors, but it came out looking like it was just an x-ray version, which I really didn't like, nor would I want to release it. So it will just take time to actually change the colors and it look good.
Yeah, don't be discouraged by any means.. I have a lot of years of experience.. Just keep putting your best effort into your work and study techniques (by practicing them) when you can... Your skill will improve.
Aaww man don't take it like that ! If you want to see the first icon I made for Jaku back in february (took it off deviantart, it was my shame xD) you'll see that all you need to get even better is some perseverance and patience. I couldn't make a decent icon. I personnally don't use tuts as decent tutorials are hard to find. But you can learn some awesme little tips from here and there to help you out one project. just gotta figure out how to use 'em.
