@ugonadie, thanks, i'll try to fix the bumps and lines so they curve more/bumpless.
@Eldricht, I should probably fade the middle grey part more, thanks.
@Maccross, I'll go in order:
Bad color choice is more of an opinion.
Be more specific, rather than saying they suck.
Again, be more specific, what sucks about it.
Where exactly do you not see much here? [The gradient in the line matching the background?]
I'll keep that in mind.
I'll sharpen it next time.
I agree.
Thanks for CC!
