Cake Painting

A friend of mine requested a cake for her husband's graduation from pharmacy school. I'm still in the process of figuring out everything, but at the very least I thought it appropriate to include the school's logo on the cake:
Originally I planned on using color flow to make the logo, but the more I thought about it, the more appearent it became that an intricate design like that would be impossible to do with color flow, at least for the size I needed.
So I sort of improvised and tried my hand at painting right on the surface of some gumpaste. It wasn't as tedious as I thought it would be and I think it turned out fairly well for my first try. Definitely not perfect but not a complete disaster either.
FYI, I didn't use actual paint (that would be nasty!) I used a simple mixture of gel paste and vanilla extract (I'm sure any type of alcohol based liquid would work, such as booze).

MWU logo. 3" diameter. I let it dry on a cake pan so it will (hopefully) fit snug on the cake.

Cake painting is a fun technique they don't teach you in the Wilton courses. I am excited to work more with it. Check out this cake that incorporates cake painting:

So pretty! Don't know whose cake it is, but it's not mine.
