My first ever foray into space art. All done in Photoshop. Took about 8-10hrs over 3 days including throwing the first version away in disgust. Not sure how many layers but a around 150ish perhaps (I merged some as I worked due to my computer running out of memory with alarming frequency). Original image size: 2600x5200. Sort of non-realistic, especially the scale of that gas giant and the clouds could be better shaped but I'm fairly happy with it.
Anyway like I said I'm new to this so comments, critique, tips and free headwear all gratefully accepted. Please full view to see details.
