I'm a beginner at gesture drawing and I had never done silhouettes before. I have no idea how these have turned out. I think they are very messy. I'm not sure if they are considered good gesture drawings, so I would really appreciate your feedback. Furthermore, I'm applying for art school and I'm putting together a portfolio. Do you think these would be good enough to include in an art portfolio?

 

This is my final 2-minute gesture drawing practice and is the one I'm most pleased by.

 

This is another two-minute gesture drawing practice.

 

This one is my one-minute gesture drawing practice. I'm not very good at drawing stick figures and I keep involuntarily going for outlining the form of the body.

 

And lastly, my two-minute silhouette practice.
