Robo bean drawing from Proko's videos along with 60 second gesture drawings

Hello everyone, haven't posted anything in too long so just something I have been practising over the last few days to improve my figure drawing and anatomy skills. Not the most interesting of images ever but it has to be done, about 6-7 hours of work. Also a quick colour study from photo reference taken from http://stefangrosjean.deviantart.com/ with permission.
I didn't spend too long on it hence why it looks pretty bad, but I am posting it anyway, we will call it a 'colour sketch' lol. see images below.
