Welcome to  FontStruct! This is a competent First Font, your sample shows that you have found useful solutions to tricky angled lines (M,N,V,X) and to keep it legible even with varying x-heights on the LowerCase. That 'hook' on the UpperCase gives a nice touch.

There seems to be a large space on 'A'  though. Maybe there is a stray brick that needs to be erased somewhere right of the A? If all is clear (even above or below the actual shape of the A) then adjust the letter space manually by moving the thick green line right of the glyph towards the left, you'll see it in menu>view>letter width.

At the same time look at the "space glyph" (between UpperCase and LowerCase on the glyph band) and  move that green line a bit more towards the middle of the width you have allowed for your letters: a slightly larger space between words would make it a little easier to read ;)  Just experiment with that line, check the effect on a sentence you typed in the  'preview'  tab on the Fontstructor's work surface menu. In that 'preview' setting you can also change the global letter space -- it changes the space (closer or wider apart) after every letter  with just one move by changing the space value with the slider in the small floating box called "spacing'.

The default space after glyphs except on the "space bar" glyph is just 1 pixel, but depending on the design of a font this letter space sometimes needs adjusting to make text easier to read. In the case of this font I suggest you try reducing the global letter spacing, then check in the preview window, including looking at the wordspace: your font has fine lines and a lot of 'air space' inside some glyphs, a wider word space will show more clearly that a word has ended.

So far you have made a splendid entry here, well done :) and because I think you have the eye of a designer and the courage to give shape to different ideas regarding glyph shapes and lines I hope you'll continue FontStructing.

Don't hesitate to ask for advice or help in the forum, we have quite a few skilled typographers here who love to hand on their knowledge to a new generation of typographers and creators of fonts. Many of our members have been making fonts for many years, a few havebeen  contributing and teaching us here since 2008. They and our younger members will also be happy to give detailed support and guide you if you encounter problems or want to explore ideas. 

Happy FontStructing :)
