Ruck, rather than trying extensions, try getting the letters to merge into themselves a bit more, at the moment you have nice letters but they are 4 individual letters, just try to get the letters to connect with each other and flow into each other. Or break the letters down a bit more, there is nothing to say the R has to be a solid R it could be made up of 2 parts like the upright and the curve, just break the letters down a bit
