Sketchbook Roses

I've loved roses since I was a child. My grandmother's name was Rose which probably had something to do with it and the fact that my mom grew them when I was young. Combine that with the fact that there are almost an endless variety of roses and how could I not love them?

I am really happy with the way the two outer roses turned out but I think the middle one needs a bit of work...
