My grandparents and the all the younger cousins crowding!

This is one of a few drawings/paintings I've been working on as X-mas presents for family, this one being for my grandparents. So, easier than buying something? NO! Most definitely not, this A3 drawing has been a two month work in progress (probably because I left it at the bottom of my cupboard for so long, out of sight, out of mind!). It's fairly grubby at this stage so...spray it with some hairspray like you do with charcoal drawings to stop it getting any worse?? Me thinks so!
