TRIPPING MOTHERFUCKING FERN LEAVES
Everything I'm going to say, as well as everything that Wayne said, can easily be summarized into "Don't fucking do it in the last 40 minute before the Flood because the result is kind of gay".
But hopefully I can actually go ahead and fit a few things about the picture that aren't obvious in there as well.
It's obvious that the picture was rushed - it shows on many, many levels, and the entire picture suffers as a result of this. this, you know.
What perhaps you didn't know that this make a perfect example of the type of shading that you've chosen to use, and its a good excuse to go out into the world and study a little "Colour Theory" - soemthing that every artist who wants to colour their pictures should look into.
You've started off with a mild colour to begin with, something respectable. But, looking at the shading below the neck, you can see that the shading goes from cool colours to warm back to cool - a mix which simply, isn't working out. Next time you shade, you'll want to make sure that yours colouring is consistent - that it goes from warm to cool or vise versa, or simply stays in one of the two regions.
The lighter green aura around the eye is also another example of poor Colour Theory - when already starting with a mild colour, it doesn't make sense to go from mild to lighter back to mild again, an it jars with the rest of the colours. When using lighter colours, make sure to use them in places where the light source would realistically hit - in this case, more likely then not, up on the dino's head instead of in and around his eye.
Course, these points are just that - points - that can be bent or broken, so long as they're mean tto be - I've seen some truly stunning psychedelic pictures while looking for art that do just that, However, it doesn't look like you were trying to bend the rules, and if you were, you might to get some practice at it.
There's also that these points don't exactly matter int he face of that the amount of rushed that you did sort of renders these previous points moot, but I'd thought I'd put them there anyway, as food for thought.
Congratulations on contributing with dedication to procrastination, spaghetti, and its a shame this Flood sort of went out with a tinkle. i kind of feel a bit responsible for that.
