Viola +Piano, short piece

I'm learning simple things as I've been going along, any suggestions, or is this too short to go off of? I'm really interested in music but haven't gotten a great place to learn, everything simple to complex is greatly appreciated.

A lot of focus on the tonic (I chord), maybe branch off a little bit more? I find that the more places you plan to go, the longer the piece becomes simply by proxy of that knowledge. It sounds like a solid opening to an exposition of something that could be expanded on in and of itself, but if you think about where you want to end up, you'll find a way to get there. :)

You have some interesting parts but it does seem like I am forced to focus more on the I chord. Branching off can really bring out that emotion between the viola and piano.
