Robot character design and colouring

Robot character design and colouring - student project

I watched a your colour video and loved the robot you did, so tried to create one. He needs a name - and I'd appreciate feedback on the colouring. I don't know if I just overwork everything but to me it looks messy and just not quite right. The video you did of the second outline layer with the gaussian blur was also another thing I used in this one, which is new to me. 

Made in adobe PS. 

Thanks in advance for any help! 


Added a second attempt at a new robot after watching your video on colour theory and lighting. Hopefully an improvement?
