Very good start but i am seeing one or two things to question.

1 why so many lines of geo through the center of the body. The sides and legs look evenly spaced out but then lots of un needed geo in the centre (from what i can see)

2 what up with the geo upper part of the upper leg - seems to be a few errors - front legs look spot on.

Hope the points help. Keep up good work

3 some more errors in geo that i spotted in first image - between horn and top of hump
