Congratulation!
I hope that the image taken by the Huygens probe on 14 January 2005 will look like this wonderfull image.
Your image seems to be realistic:a sea of hydrocarbons with impact craters.Thanks to this deep and thick atmosphere, I don't think that there are as many craters on Titan as on Tethys or Rhea.
Is Saturn visible through this opaque atmosphere?On that point, I think your artistic view might be close to reality!
I invite you to visit my website devoted to Titan (with a view of the surface of Titan):
