Vectored version of my first EQD ATG sketch (can be found here:
[link] ).
Have to admit on the sketch I made it rather easy to spot really terrible mistakes. For example: I placed her crown in front of her horn, wrong angle of horn in general, kinda short wings (for my taste) [but I actually just run out of space on my A4 paper (same with mane and tail) – DERP].
On vector I fixed all of those mistakes also reviewed armor design a little bit .
I especially would like to thank

for this color palette
[link] which I used in order to make this vector. If anybody interested the actual Princess Celestia pose almost like that (aka what I used as reference for a sketch) could be briefly seen in season 1 episode 23 – “The Cutie Mark Chronicles” when she is about to rise the sun.
Would be really nice to see some feedback – thank you.
P.S. Making her her tail/mane and armor strokes was especially fun well that just by the way...
P.P.S. Yes really I did freehand it.
As for image size I started project as 6000x6000 since scanned version of sketch was 3400x4680 and then I just increased it since I wanted to make wings bigger. But at any rate that is the whole beauty of vectors – they made of shapes which is not affected by the scaling process so the quality will never diminish.
