It Keeps Getting Better
They say practice makes perfect and nothing illustrates that better than these comparison pictures. The OP who is an artist (surprise, surprise) promised her boyfriend that she would make an epic painting for his birthday. The first one she made was in 2006 and while it was relatively simple, you can still see her talent shine through.
From then on, she just got progressively better as you can see from the second one from 2016, and the most recent one from 2020 which is nothing short of epic! She has clearly honed her skills and learned a thing or two over the years. That last dragon took our breath away (no pun intended).
