To start a few side comments: First, the ship on the far left is from the Star Wars universe not Star Trek. Second, if you used a referance it needs to be posted.

As for the piece, it lacks focus and the two ships have no decerable relationship between them. Also, the moon is either extremely large or the Enterprise is even larger then the moon. Perhaps I'm completely missing something.

cool space

@ Ioneorbit:
thanks for the critiques but:

1) isn't its name "science-fiction"?
So who said that, given that we are talking about a "fantasy" genre, you can't mix up Star Wars with Star Trek? Are you telling me they are not contemporary? or are you able to tell me exactly he historic (futuristic) periods their stories are ambiented?

2) references: http://www.capital.it/trovacinema/pop_gallery.jsp?idContent=289905&i=2 for the starship on the left and http://talk.trekweb.com/tvguidescan02_enterprise.jpg for the Enterprise ship in the center

3) the ship on th left, really more little than the other one, is going away from the Enterprise, as the little text in the description says, that is going adrift. For me it's natural viewing the ship on the left bigger that the Enterprise as it is on close-up and what's the problem to have a huge moon? It's not our moon...

@Goldstyles: Thank you

Not bad..Perhaps a little bit more brushwork, and blending in the ships some more, would give an extra level to it?

what part is manipulated? looks liek you just cut and pasted the ships on there, plus are those photos you shanked Royalty Free or did you just violate George Lucas' copywright ehehhe.. beware the Dark Side of Copyright infringement LOL

On a side not the planet looks good, but then again did you make it?

Nice one, I'd simply suggest to not overdo the lensflare
