I somewhat disagree with the existing answers and think the fundamental problems are these:

*	The *d* has lost too many properties fundamental to a *d* and the Latin alphabet in general:
	*	The bowl is too big and too thin in comparison to the stem.
	*	The bowl goes below the baseline – which is established by the rest of the text as well as the stem sloping away on that level.
	*	The opening is at an odd place, if not a wrong one: You would never leave a gap there when writing such a letter by hand, but instead put it at the upper collision of bowl and stems.
	
*	By form and spacing, the stem of the *d* integrates into the rest of the text like a letter. Except for the leftwards bend at the bottom and a bit of extra space on the left, it is exactly like you would expect an *l* at this position to look like.

To somewhat illustrate this, consider the following alternatives:

Mind that these are still not good by far, but at least you have a decent chance of decyphering them as intended: It’s either *dahua* or *adhua* and the colour or special position of the *d* make it clear which one is the intended reading. In the first case, you will first read *dhua,* which probably doesn’t fit your expected orthographic conventions and on a second glance, you will see the *a* to correct it. In the second case, you first read *ahua,* at a second glance you will note the *d,* and at third thought you will know where to place it.

The fact that there still is a decent chance of misinterpretation and you need a second glance and some mental work to avoid it, is of course still a problem.
