What is the central idea of your concentration?
My idea is to focus on skulls of both humans and animals by layering and using details.
How does the work in your concentration demonstrate the exploration of your idea? You may refer to specific images as examples. When referencing specific images, please indicate the image numbers
As I have progressed, I have used more layering and have payed more attention to detail. My picture with animals skulls and the mountains in the back shows a lot of detail. My most recent picture shows my use of layering. 

Concentration Check Up

My concentration is skulls and bones but I've taken it toward the more serious perspective rather than trying to incorporate humor into it like I did at first. At the moment, I am stuck and am not sure what to do next. I feel like my repetition and layering of bones has been working, it's just the fact that my pieces do not look complete is frustrating. I am also trying to simplify my pieces because I've been told I try to complicate my pieces too much.

This is my piece from out last critique. From the comments I got on this, it seems like people do not think it looks complete, but they like the contrast. I'm not really sure where to go with this one because I'm not sure how to make it look more complete. Also, I'm not a big fan of the black on the left side and I want to find a way to make that look better. I think it is too bold and just isn't working.

If anyone has any suggestions for ideas on what I should do for my next piece or how I should improve this piece please let me know! Thanks!
