Today I bring you Rhonda, Phoebe, Helga, and Lila as teens! After drawing them in my own style I thought it'd be fun to try show style - and it was! (It's more straightforward and unified than the Dexter's Lab style. )
I tried to stay true to all their styles while still aging them up, and I hope to do one more series of them as teens. There's also more on my Tumblr, [link] including a variation of Rhonda and a drawing of Curly (who I couldn't add here, haha).
And not my favorite choice of background, but it looks like the old Nickelodeon promotionals and I couldn't think of anything else anyway...
