Well, I just made this simple little drawing with paint. Hope this never happens but what kind of program can I use to make this look better? Here it is though;
Well if you want to edit the current picture then you can use the editing tools in photobucket.If you want to draw a better version then you can download and use GIMP which is free.Although Photoshop would be a better program if you are willing to pay for it.
Making the shadow transparant, so it is not black, but only darken the earth a little, Making shadows in the water and other colours on land, the comet either somewhat flaming, or as any other comet, flaming with ice. Make the background better, so the stars are not the same size and opacity.
Make a new layer, redraw. Make a new layer for each of the parts coloured, fx for the land on the earth, or the comet. Use a good brush for the solid colour, use the airbrush for shadows, and the smudge tool for fire and the stars.
