You should post to another more commercial site like FAA (fine art america). This site is great for maturing your work to a point where it will be ready for commercial display.
The work itself is great, and it doesn't lose anything for not being drafted to perfect 3-point perspective. It would look good with that style of accurate perspective, but I think context will be a better selling point. I'd say maybe paint-in some dog treats in her hand to relate the girl to the animals. It's up to you, It's just an example.
