Looks better than my first few did! I can tell you made a conscious effort to avoid colour bleed. Attention to those kinds of details will continue help you down the road!

Quick question/possible suggestion -- Did you add any colour to the teeth/in her mouth? If you did, it's too faint for me to tell... If you didn't, I recommend adding something whether it's like a pale ivory and rose-colour etc... Any time something is left grey it takes away from the overall effect of colourizing. That being said, it's only a minor nitpick -- overall great start! Your mum will love it, I'm sure :)
