???Really Frustrated- Can't get Gifzign even started with my image. Please help


I am using a Mac - and am new to Gifzign.  I am unable to move the S and the E.  I am using an image  trying to make it into a Gif.   is there some trick to moving these .  - As long as I am asking - please tell me again --   The brush is what you want still and the eraser is what you want to move?  On the image attached - I was trying to get the clouds to move -and couldn't get that to work - so I tried the road.  The gif I produced just seems grainy now.  thank you 

I am really excited to get this to work.   also can we make a jpg from a Gif?    hope you can help.  :)
