Hihi! Great question! It's a stylistic choice! When I draw objects that exists in the world, I dont draw the outline on the bottom of them! If this isn't your preference, by all means, feel free to modify them to suit your needs!
It looks great! just wasn't sure if it was meant to look like that for marketing or something :D
Oh! Thank you! And thank you for pointing it out just encase it was something I overlooked too XD
