Thanks Mike,I struggle with just how much is too much detail. I think I'm learning to get to the "just enough detail to give a realism but not too much" but still struggle with it.
I had considered printing cards, the owners are fine with it. It has been tough to get lighter areas.... I'll have to think about this a bit more.
I have visited your site a few time after coming across it not long ago, wow.... Thank-you for having a link to the ArtPopa site, I would never have stumbled across it on my own I think. It has been so wonderful to see a community of wonderful pencil artists, I had no idea! And to be able to share ideas, etc. is even better.
Thanks again.
