Phew, this took long. But it's worth it!

I'm gonna make a high resolution version of this for my soon-to-be-born niece to post on her wall as a painting.

I think Celestia's hair took the longest because I couldn't figure out what to do with it. I wanted it to transition into the sky somehow. I like how it all looks.
Also the contrast difference between my desktop computer and laptop annoys me.

Enjoy, fellow Bronies.
By the way what's the lesson being written on the letter?
