I'm sure you all had that moment after the first time you painted in which you felt so good, or maybe it was only me, I just had a very good feeling afterwards, that, here, I'm finally progressed from having only minis and now became more serious about 40k

Just let me remind you that that was my very first time! I of course accept C&C but please don't expect this to be 'Eavy Metal
For what I did:
The carapace:
Base colour was Chainmail, then I did a 50:50 mix of Mithril Silver and Shadow Grey and then highlighted with Ice Blue, later I also washed it with a very very watered down Asurmen Blue, which took down the metallic look, so it was a mistake.
Note: These colours were my friends so they were GW, I bought P3 colours (which are absolutely awesome) well because they were cheaper but comparing them with the other colours my friend has, I think they are better than GW paints. If you never touched P3, I'll translate it into GW
So for the flesh the base colours were a mix of Battledress Green (which in GW colours would be a more darker Camo Green, like an olived tinted Camo Green) and Battlefield Brown (Darker Graveyard Earth), these two together gave it a very earthy look, I highlighted with Thrall Flesh (a bit greener Rotting Flesh).
For the talons, I painted them with only Battlefield Brown then highlighted them with 'Jack Bone (a more grayish Rotting Flesh), that was really hard though, and I'll need to get better with the talons, highlighting those little things was really hard, but I guess that with bigger 'Nids with talons it would be an easier task! I also added a bit of Scab Red at the end of the talons so it will look bloody, it was OK I guess...
I painted the teeth with 'Jack Bone and then I washed the whole body (Flesh + Teeth) with a 50:50 mixture of Armor Wash and Brown Ink, both together proved to be an awesome mix and worked very well
All in all I think I'll make the carapace lighter, and instead of Chainmail and Shadow Grey I'll mix Chainmail and Ice Blue, and then highlight with a mixture of Ice Blue and white, or only Ice Blue as it would be lighter anyways than the Chainmail + Ice Blue, but I'll see
