Looks good so far The corners on either side of the control panel in the background should be a tad brighter with turbolift doors. Also the base of the control panel in thebackground should be grey, not the same colour as the walls.

Control panel itself should be wider ceiling very center should have a small dome facing inward that looks out amoung the stars.

Sorry just my inner Star Trek geek is coming out with full knowledge of the TNG style Bridge..

Otherwise it's mostly pretty good. What App you using to draw this Puppy? BTW when you go to do the railing behind the captains chair where Worf would usually stand, Make sure to make the upper portion with the computer panel on it is a nice bright brown/dark orangish colour to represent wood since the original piece was made of wood.

Sorry my inner Star Trek Geek came out with my utter crazy knowledge of the TNG Bridge. I'd also mention the other side panels on either side of the turbo lifts/ Ready Room but looking at image they won't show up much so won't be as big a deal to mention.

Anyway it's good work Puppy. Really good. What art application are you using for Android might I ask?

Smart Paint
Noprob I love star trek too!

Ah Ah alright. Yeah whenever I'm on my Galaxy Note 10.1 (original from 2012) I tend to use Layerpaint HD. It's an $8.00 app but well worth every penny. Might wanna look into it for your next Drawing or for your next tablet. :3
