Birthday Present for my mom

My mom requested a drawing of all her kids from me recently, and since her birthday was yesterday I figured this was the perfect opportunity to give her exactly that

If you're wondering, that's me on the left, then my older sister and my two younger brothers. 
They are both half-brothers though, so that's why the haircolor is so diffrent

Even though this was for my mom I also really hope y'all enjoy it too!
