Yes. My first ones, the originals hangin on my apartment wall, aren't as detailed as the ones I did last year. I just got the ideas in my head then 'erased' them on paper. Sort of a reverse thing I guess.
The ones for last year, I used a couple of photos, one for the lion and one for the wolf pups, to created those. The dolphin one I did last year was the re-do of the first one. I didn't like the first one so redrew it and liked the second one much better.
I will probably be using some photos this time around too for more inspiration. I have a few ideas already floating around in my head for those.
Yeah... I know I may not be the first to do any of these, like with my erased chalk ones, but I haven't really seen any either from others. So, we will see. I like creating new things. Mainly just to see if I can do it.
