You would need to post better photos, both standing for confo and moving, to get a better evaluation.
From her previous endurance work, you know that she should stay sound and can handle an eventing training schedule.
She's overjumping the little crossrail, and is fairly good with her front end, work would probably improve that and she has the right cheerful, bold attitude about her fences.
However, the draw reins in the flat photo concern, partiuclary since she's braced up against them and not yielding at all.
So, the big question is, will she accept the discipline and flat work necessary to produce a decent dressage test? It the answer is yes, well then, she'll make a good lower level/local level event horse.
Then the other question you have to answer is based on what her selling price is - is their a better prospect out there with less reclaim work needed for the same or similiar price?
