A plant preserver robot

The plant preserver robot-

A robot working in a plant conservatory & programmed to take care of them.

Had to model and texture the robot in a short period of time as I started late; 
So, here's the final composition I made with the robot. Feel free to share your thoughts on this.

Some renders to showoff the final pose of the composition

made a simple rig for the robot and setting up a composition

Made some plants also made some adjustments to the texture, I think it gives more clarity as the imperfections are easily seen

Test render made with blender... gotta make some flowers now..
If you come across this update pleasee comment how can I improve or provide any suggestion

Modeled the robot and started texturing on substance painter... Not sure about the color though...Should I change it?
