At first I was rather disappointed with what I saw in this thread, but, since inkthinker came along, that's no longer the case. Do you mind if I use one of your images as a wallpaper?
Sure, I don't mind, I generally size them so that they work for that. I suggest making your desktop's background color either black or white (whichever looks better to you) and setting the image to "Center", which is what I usually do.
I wouldn't say anyone else's work in this thread is disappointing... I do this for a living, 8 hours or more a day, every day of the year, so I have an unfair advantage in the realm of illustration. I love my work, but if anything I think the other artists in this thread love their work more... they're not doing it so much that it becomes old hat, and they show more dedication and guts when putting their work in front of the world at large than I do.
If you love something enough to draw it, especially when you're not a professional artist, then I want you to pick up the pen and give it your best shot more than ever.
