So here's my own season 4 design for Danny. He's in between the stage of prepubescent shortness and becoming tall and lanky. As I've said before, I think he gets tall before he gets buff, in human form anyway. Ghost form's a different story. He also has a little mullet.
His human outfit is slightly based off of Fun Danny's, minus the hat. Either that or he's been hanging around Michelle too much XD
Ghost form, I decided that he would want to ditch the hazmat suit after a while. The one he had on doesn't look like it would grow with him. The t-shirt he's wearing is just a smidge inspired by Dan's outfit, and his pants are different too. If you look closely, he has silver/white stripes going down the sides, like workout pants. It ain't a coloring mishap C: and his boots, hardly changed.
I might do him in the later years as well, along with Misty and Michelle.
Background's random as usual! I like messing with effects and filters too much.
Yes, I like The D on his human form shirt is kinda weird though... Other than that, it's amazing! Guys+Plaid=hot XD And the ghost form is freaking perfect. I like how it kinda resembles Dan's costume a little bit, but not to much. Beautiful!
