First sketch/WIP for the year

So I was walking going back to my apartment from school and passed by a bank and saw this muscular guard in the front and his body just bulges on his somewhat tight uniform (yeah the way I drew this character's clothes is somewhat he looked like)... he kinda resembles a SWAT team member with his physique but if course he's just your typical security guard. so I was sneakily looked at him for a while and

"ding!" INSPIRATION!

...and thus this illustration...

Bantay (pronounced as "Ban-tai") is Filipino word for "guard"

I had to look for dogs on the streets and on Google images for a design and kinda jumbled it alltogether... as for colors, I'm still undecided but as fpr the uniform color, the common navy blue uniform.
