The thing with fonts is that you really need to have a template to work with.
The symbols you're having problems with are common issues with any pixel based font. the W's, the M's, the Q's, etc
Also if you want to be truely old skool you should try and squeeze the font into units of 8 pixels, that's 8x8, 8x16, 16x16 - this is because everythign used to be done in character mapped screens... but that all depends on ones definition of old skool obviously... to some people spyro the dragon and croc is old skool, to me old skool is commando and galaga and space invaders.
anyway... have a look here...
I've highlighted inconsistencies in your Bigger font in green pixels... Look at the width of the B C and D - the b is 2 pixels wide, the C is 4 and the D is 3... then look at P... where the upper section is 2 and the lower 4 pixels... now generally speaking (unless you're font is DESIGNED to be irregular) then these parts I've hilgihted should be of a consistent width or style.
Typography is a highly specialized field of graphic art and one could go on forever about seriphs and kerning and leading etc etc... but I won't. The basic rule is consistency and the only thing consistent in your font is the copper banding gradient... which is very old skool I must admit.
Moving down I've illustrated in blue how one should begin any font... with the symbol '8' - from this you can create most other symbols. with the exception of W's and M's, I's and T's... (there's probably others) but point being you need to consider these too and besides... 8 is a good starting point.
Also, I've aligned them to an underlying 8x8 character grid - force of habit for me I'm afraid... but good rule of thumb for creating fonts... helps to be accurate.
I've also done 2 additional scales, 8x16 and 16x16...
The examples (in white) are for the letter A, and M, X(traditionally tricky) and the number 2... followed by the entire uppercase font in 8x8 - I've not ripped that font, I've created it on the fly in minutes using the technique described... it's no way an inspired font, it's not clever or stylish by any means... it's functional and fast to make and easy to read.
And finally for 'old skool' sake, I've added the gradient and a 1 pixel drop shadow (which still fits into the 8x8 grid).
So, what I suggest to you Noveroth, is to go back to the drawing board and rework that big font... the little font is fine, it's excellent in fact. The Big font you need to set yourself a template and stick to it... it doesn't have to be fixed to 8x8's like I've suggested that's just me... it can be any size, just make sure it's consistent...
Have fun.
Cheers
