Make few Pixelart assets for a platform game (16x16 size)

ATM we are using this unity game asset : [login to view URL] These are 16x16 tiles and we need more arts to end our development. of course, we will need a very few sprites too. think that you are going to do small work, few arts for this work. we will need : pipes (we have a set in non pixelart style, you simple need to convert to pixelart) gears ( 2 at least, diferent sizes ) belts and pulleys ladders doors and hatchs in metroid style ( with animation frames, can be simple ) An terminal screen to be used in game, think a mix of fallout 1 with talos principle terminals one simple char ( think about a floating amoeba ) with 1 animation frame to frame of they standup one char to be the main protagoist : a 16x32 animated one with these animations (sprite sheet) : walking running jumping jumping with a little propulsion swimming ( 32 x 16 instead of 16 x32) doing a dash ( like megaman X) stand up , but show the backside stand up , but show the frontside with some heat protection with some cold protection with oxygen tank upgrade Using a Ladder that´s it,
