Sketch Challenge: Monsters, Part II

I just finished up the first week of my sketch challenge and am feeling so refreshed from doing these quick drawings every day.  

Here are the last four days of sketches:  

Monster #4 

Monster 5 

Monsters 6 an d7 

I know a couple of you mentioned that you'd like to participate in these little sketch challenges as well.  Feel free to do so!  I'll be starting a new topic every couple of weeks.  If you'd like to play along, be sure to leave a comment below with a link to your blog/website/etc.
