I'm new to modeling. I working on a star wars model, a AT-ST. I tried cutting out the front windows with a hobby knife, but I made a couple of bad mistakes. I have a couple of knife cuts on the face of the model. The window hole is in bad shape, it's not striaght and the shape is funny looking.
I need help in repairing my mistakes. Does anyone have some advise I can use in repairing this damage?
