Good i guess
I'm really not a big fan of scene makers. If i wanna do such things i go to MS paint and make comics and do other stupid stuff with it. Out of the scene makers i seen this is a pretty good one. Maybe make so you can change the background or change the music. Or add a text box. A title screen may help or an intro would make it feel nicer. If you could do some of the things i said you got yourself a pretty good scene maker. Good job. Just think a little more next time.
