Ha Ha! Isn't that crazy? I know my ideas were similar to a couple prompts posted, but I think I was just overwhelmed with the scope of the prompts all together. And thought that it was calling for something quite complex. I particularly remember the different human poses expressing different emotions. Wow! I was intimidated by that and didn't even want to try. Partially because examples given had attempted so many! And then one called for different objects - lots of them, I thought - to portray something like abandonment for instance. Yeah, that seemed like a major project for me.
Now, I don't particularly remember the objects under different lighting one, but I'm thinking of something like a ball, or a shoe, or a seashell or a hairbrush. One very simple thing maybe with lots of light and one with little. Or from the left vs. from the right. Perhaps your prompt was that easy, I'm sorry I just don't remember it. ANd I think that's because I get a little intimidated reading the post. Sorry.
I don't draw anything, hardly even doodles, without some sort of reference at least as a starting point. That's just the way I am. So for me, the drawing humans prompts would all involve searching for reference, anyway. But I have lots of pictures I look at all the time when searching for inspiration.
I'm sorry I missed the one about making the negative spaces - the blacks and shadows. That sounds great to me. It's one I'd probably attempt.
I'd love to draw a little something every day. That's why I was drawn to these posts in the first place. But all of us work a little differently and have totally different comfort zones, I guess. Hmmm.. I wonder if posting them as easy/quick ranging to harder/more involved, and having only one example of each? Also, I'd be glad to hunt down some ideas for more abstract prompts. I prefer semi-abstract anyway. You know...it actually looks like something! LOL
Also, I bet lots of people want to participate, they just don't want to all the time, and are waiting for a suitable prompt or the time to do it. There haven't been too many posts, yet, for us to choose from. Give it a little more time and I bet you'll see more participation.
