Im here to be honest, So here i go,
For the Vision, i believe it looks nice, But im having trouble deciding what color the eye is.. Black?
You COULD clean up on the outline a bit. (im just saying) So far i really do like it, Its much better than my drawings of ponys, For orginality, i have to say.. its.. 'orginal' but not.. exactly.. It looks sort of like a recolored rainbow dash (no offense of course ^^) when you redraw it, i suggest you try a diffrent mane style. Technique here is common, I really like it. And the Impact, i guess that means how it made ME feel, was its very pretty, the colors go well together.
Also, When you ever go to draw like the actual show (only if you're going to) try outlining it ina darker color than the body.. Of course you dont have to, but its just a suggestion,
and for another thing, Does it have a cutie mark? or is it a filly?
Anyway, awesome job~!
