Well first off, my name is Ricardo Brown, and I've been lurking on the forums for a while now. But I think it's about time for me to start a sketchbook thread here as well.
Any critiques and comments are always welcome. I love to receive critiques from other artists and to find out anything I can do to help myself get better.
I'll try to update this as often as I can with new sketches, and finished illustrations I've been doing to improve my portfolio and grow as an artist.
