Hi @Georgios-Christopoulos I really like your comic style; it's very clean without being too clean (if that makes any sense...).
My only critique is that the city was probably the last thing that my eye went to, and based on the text, I'm assuming it should be the second or third thing. I think the size is good, so maybe it's that it has less contrast than the other items in the area (or maybe if you want the outpost to be featured more ((given the prompt)), make that more prominent and give it more priority in the text).
(Also, I really love your snowboarder for the slippery prompt)
