I think the red should be a similar size & weight to the black. What is the reason for the handwritten look of that letter?

hi,i believe that the handwritten look
gives the character of the manual job...

I concur that the handwritten Ε is a little weak. There's no need to make it as bold as the black text, because the red already add to its visual "weight". But a little bolder/larger should be better (I would made a little less thin the 40 too).
Also, I think you should align all the red text to the vertical center of the black one and not to the baseline as it is now.

i'll try to make the red letters egual only in height
and a little bit bolder,i'll also try to make something
completely different(based on the shape of a carpet)...

If you're going to go with hand-drawn 'E's, go with actual hand-drawn 'E's. Because they're exactly the same, they don't look hand-drawn. Get out the India ink and a brush, and make eight strokes.

If you feel the need to use a font, don't go with one as readily available as Bradley Hand.
