Look, don't use a mouse. You already regret it from the sounds of it.
You're better off saving up money to invest in a tablet or an ipad with a stylus (there's an app that allows you to connect your ipad to your computer and it allows you to use it as a second screen which is SUPER handy when it comes to drawing. However the name of it actually ceases to escape me for the moment.) Until then I would take Cloud6625's advice and get pixly and a stylus until you are able to get the resources that you do need.
But what everyone said stands true. These aren't even worthy as something to be called "custom" since most pixel artists tend to look at customs as something done from nothing. Otherwise known as doing something from scratch. The harsh truth is that, while we know that you can do recolors or edits, frankly a lot of people who know better aren't going to look at you very highly if they know what these are at face value. That isn't to say that you're a shit artist, but you're doing something that literally anyone can do in minutes, maybe even seconds. The point is that in the professional world let alone a community that has had it's roots embeded at making sprites as an art will tell you that these sprites aren't really much of anything.
Take a few steps back, think about what you can do besides pixel art and make traditional drawings just a pencil and paper and study up on some foundation skills until you're able to get a hold of a stylus. You'd be surprised how skills taken from studying traditional based art can translate into digital art based mediums such as pixel art/sprites or even vector based programs like illustrator, but what's more important is that your putting yourself in the practice of making something just from your imagination and working you're creative skills. It's better than trying to put yourself in a defensive position over what you are doing right now, That I can guarantee speaking with experience.
And if you are truly, truly willing to go these lengths, do not be discouraged by the criticism we give you! If you really have the drive to make art, you will have the drive to learn from more experienced users and eventually learn from your own mistakes.
