Last moment

I know I have blogged but that's because I didn't have much to write about. I'm still only managing to draw a page a day sadly. Really trying to push myself though. So recently I was hired to do a commission. I was almost finished and the client tells me they changed their mind and they want something different. The first logo will no longer be used and now I have to create something totally new. I feel like I should charge her again right? I mean I'm completing two of them are and even though only one of them are being used I should be compensated for my time and effort right? I already got a deposit for that piece but it's still frustrating you know? I'll probably auction of the logo on deviantart.
