I've been downloading skins here since 2007 and Love all the wonderful artistic talent I've seen with all of the skins.
I've only had one occaisional problem and it may be the contrast level of my monitor. In a few of the skins I've downloaded, the contrast difference between type color and element background has been a bit close so it makes it hard to read some of the type. I know how hard it is to get a good contrast because some of the best designs I've seen out there have background elements with different gradients or wide shifts in hue.
My only request would be that font color and background color be a bit more contrasted so it is easier to read the type instead of what I usually do, Pull the monitor closer to my face and rub my nose in it Lol.
Please don't this is anything more than a request, after designing a few skins myself, I know how hard this can be and my design skill are just starting. I just picked up Photoshop ans SKS 9 months ago and still have years of learning to do before considering mself a decent designer.
I look forward to seeing any response to this thought.
